Re: Baking Question

Not STYROFOAM peanuts!!!!!
You probably heard of using the biodegradable peanuts (made from corn
starch or something) to cradle odd shaped pieces. These peanuts are
water-soluble and can me "molded"  to conform to what you are baking.

I generally bake my pieces on glazed ceramic tiles, usually covered
with deli paper. Without the deli paper, the bottoms will often pick
up a shine from the tile, especially if is is glossy. You can get
cheap tiles at Home Depot, Lowes, or other similar store; they come in
a variety of  sizes.
In addition, I think the tiles contribute to more even heating.

The downside of tiles is that they are heavy and break easily if
dropped.
I'm considering using mason board/hardboard; it's cheap, flat and
lightweight. If I can only figure out how to cut an 8'x4' slab into
small pieces!

I avoid cardboard or wood because those materials will warp, and metal
pans because they often are not completely flat.
These issues may not concern you, but for most of what I make - a lot
of boxes - I need absolutely flat bottoms.

Good luck.
